It is well known that electronic technology advances very quickly, with products being outdated and replaced by a newer version every year. More and more frequently these subsequent versions of the same product are being called ‘generations,’ such as a ‘5th gen iPod.’ Nest Labs’ range of ‘smart home’ products is no exception to this trend and the oldest two have already undergone a few iterations of redesign and improvement.

This guide has been written to help you quickly and easily identify which generation your Nest Products belong to.
